1/2A Combat jobs from the 70's, 80's and the 21st Century...

(1/1)

Paul Smith:
I just did the final assembly (can't say "build") of my first new combat plane of this century and millenium.  While I was K-balling the engine department from my oldies, I took some family photos.

The "Pawn" from the 70's weighed 5.7 ounces & has 178 square inches.
The "Mini Monarch" of the 80's was up to 6.3 ounces and 188 squares, but it handled a lot better with the taper wing and higher aspect ratio.

The new Viko weighs a whopping 7.5, but has 283 squares. 

Aside from final assembly, I was compelled to redo the leadout guides.  They were too tight, so I swapped 'em out for some bigger eyelets & had to reterminate the leadouts.

john e. holliday:
Hi Paul I see you are using a MECOA conversion head.  Is it working okay for just general flying?  Later,  DOC Holliday

Paul Smith:
I dunno.  Haven't fired it up yet.  I also have two other styles of conversion heads.

Pretty soon, I'm going to do tach tests with all 4 or 5 types of Cox .049 heads that I have.

The racing guys say the Cox high compression head is still the best,  but that option (with it's $11.95 price) may be extinct soon.

Paul Smith:
I tried to run that RED anodized head.

Lesson 1: 
If you want to get plug to light, clean off the anodizing at the plug seat and and gasket surface. 
That red stuff is a great insulator. 

No tach readings today. The test engine was unworthy.  Not the head's fault.
